Galaxy rolled out an energy-efficient GeForce GTX 650 graphics card, the Green Edition. It is one of the very few GTX 650 graphics card models that lack 6-pin PCIe power connectors, and rely entirely on the PCIe bus for power. The card uses near-identical PCB and cooler designs to the GTX 650 GC, except the 6-pin power connector is absent. The card sticks to NVIDIA-reference clock speeds of 1058 MHz core, and 5.00 GHz memory. It packs 1 GB of GDDR5 memory across a 128-bit wide memory interface. Expect the GTX 650 Green Edition to cost around US $110.

does any one know if those GPU are rejects from production as not stable enought and then downclocked?
I wonder why other vendors just don't offer no pci-e 6 pin connection to boot but still have the connection onboard for oc purposes?
